Subject: [PATCH 0/4] STi device-tree display subsystem rework

This serie aims to rework the display-subsystem node, which was
previously included directly within the SoC node.  This was wrong
because it is an abstraction and describes how IPs behave together, not
what the hardware is.  Instead, extract display-subsystem outside of the
SoC node, and let IPs describe their connections.  Doing so helps the
readability, and eases the understanding of the hardware.

Several nodes have been renamed to stick to the generic names defined in
the device-tree specification.

This series depends on another sent a few days ago.  It is not critical
though, since not having it only triggers warnings when building
deprecated device-trees.  Please see link below.
